COVER 



Halley Hot Line 



A new Comet Halley Hot Line, to keep fans of the return- 

 ing comet on top of its whereabouts, went into service 

 on December 15. 



The new high-volume commercial service allows 

 several thousand callers at the same time to hear a re- 

 corded message about the comet. The information is 

 provided by the United States Naval Observatory in 

 Washington. 



For people anywhere in the United States, Canada, 

 Puerto Rico and the Virgin Islands, calls to the telephone 

 number, (900) 410-8766, cost 50 cents for the first min- 

 ute and 35 cents a minute after that. 



The recorded messages will be updated regularly, 

 talking about the whereabouts of the comet — making its 

 first return visit since 1910 — and telling callers how to 

 locate it in the night sky. The hotline is expected to re- 

 main in service until April 15. 



The piebald saki, Pithecia albicans Gray, of the upper Amazonian 

 region of Brazil, painted by Zorica Dabich, Field Museum staff 

 illustrator, for Living New World Monkeys (Platyrrhini), 

 Volume 2, by Curator Emeritus Philip Hershkovitz. See pages 

 24-25.
